[future request] snappyHexMesh: 'std::out_of_range' error

Summary

The following error occurred when testing on the supercomputer Fugaku Pre/Post node (large memory(6TB on board)).

[error messages] terminate called after throwing an instance of 'std::out_of_range' what(): stoi

It appears that the information on the size of the memory could not be expressed integer range.

Example case

Steps to reproduce

[tutorials] tutorials/incompressible/pisoFoam/LES/motorBike/motorBike (When snappyHexMesh is executed)

$ ./Allrun

Environment information

• OpenFOAM version : v2306, v2212, etc
• Operating system : RHEL 8.6 (kernel 4.18.0-372)
• Hardware info : Intel Xeon Platinum 8280L (2.70GHz/28core)
• Compiler : icpc (ICC) 2021.10.0 20230609

Possible fixes

Changing the stoi function in src/OSspecific/POSIX/memInfo/memInfo.C to the stol function will terminate successfully. This correction was found by Fugaku support staff.
